An Unusual Appearance of Meckel's Diverticulum as a Site of Bleed on Gastrointestinal Bleeding Scan.

Lower gastrointestinal (GI) hemorrhage is a frequently encountered and challenging clinical problem. GI bleeding scans are extremely useful for localizing the source of GI bleeding before interventional radiology procedures. It is essential that physicians understand the numerous possible pitfalls when interpreting these scans. Understanding the potential causes of false-positive scan interpretation eliminates unnecessary procedures for the patient and minimizes costs. We report a rare case of an 8-year-old boy who presented with GI bleeding. Upper and lower GI endoscopy did not reveal a source of bleeding. We emphasize case of Meckel's diverticulum appearing as a proximal jejunum false-positive site of bleed on bleeding scan. In addition, we reinforce the criteria needed for diagnosis of GI bleeding site on the nuclear bleeding scan. A high index of suspicion is the most important diagnostic aid that can prevent the nuclear medicine physicians from misdiagnosing the site of lower GI hemorrhage.
